Meter Panel - Yamaha PM-1000 Manual

METER PANEL 1

A. MAIN (PROGRAM OUTPUT) VU METER Four
illuminated meters that provide a visual indication of
the average audio output level from Master and Monitor
modules 1 through 4. Depending on the setting of the
function switch, each meter displays either the Master
(Line Out) or Monitor Out level. A zero VU indication
is equivalent to *4dBm output into a 600-ohm
termination.

A. POWER FUSES Protect the primary (line) and
secondary (low voltage) portions of the console's
power supply.
B. POWER CORD CONNECTOR Accepts the AC
power cord provided with the console. PM-1000 con-
soles delivered in the U.S.A. and in Canada are equipped
with grounded (3-wire) AC cords for connection to 50
or 60Hz, 110-120Vrms AC power mains. The console
draws about 45 Watts, or 0.5 Amps (90 Watts for
24/32 consoles).
C. MASTER OUT & MASTER IN Provide a patch
point between the program input to the Master and
Monitor module and the input to the Direct/PB switch.
The jacks are wired to accept standard phone plugs.
Their nominal operating level is -20dB (for high
impedance circuits).
D. LINE-A-OUT AND LINE-B-OUT JACKS (PRO-
GRAM MIX OUT) These are redundant outputs.
Line A and B each consist of four jacks, and the signal
is derived from the Master Faders. The nominal output
is +4dBm (for 600-ohm termination), and the con-
nectors accept XLR type 3-pin female plugs. *
E. MONITOR OUT (SPEAKER FEED) JACKS Carry
the console output from the Monitor Mix (Speaker
Matrix) section. Each Mon Out jack, 1 through 4,
carries audio from the correspondingly numbered
Monitor Master control. The outputs are nominal
+4dBm (for 600-ohm termination), and the connectors
accept XLR type 3-pin female plugs."
F. CHANNEL INPUT JACKS Numbered 1 through 16,
the Input jacks accept audio from any low impedance,
balanced or floating audio source from -60dB to +4dB
nominal level. The inputs are balanced and trans-
former-isolated, but auxiliary matching transformers
tSee Section 8 for 24/32 Consoles.
B. METER FUNCTION SWITCH Two-position slide
switch allows use of the associated VU meter for
monitoring either of two console outputs, Master
(Line) or Monitor. The Master indication is derived
from the Line Out A jack, and the Monitor reading is
derived from the Monitor Out jack that corresponds in
number to the VU meter.
C. ECHO OUTPUT VU METER Two illuminated VU
meters provide a visual indication of the signal level at
the Echo 1 and Echo 2 outputs. When driving monitor
(foldback) systems from the echo outputs, these meters
indicate the stage monitor level. A zero VU indication is
equivalent to a +4dBm output into a 600-ohm
termination.
D. MAIN POWER (AC ON/OFF) SWITCH Pushbutton
alternately switches the AC power on and off. No audio
passes through the console when power is off.
are recommended for unbalanced, high-impedance
inputs. The connectors accept XLR type 3-pin
male plugs.
G. SUBMIXER INPUT JACKS Numbered 1 through 4,
these jacks accept audio from a low impedance, low
level source, such as the Yamaha PM-400B mixer. The
Sub In jacks are designed for nominal -20dB levels, and
accept XLR type 3-pin male plugs." Audio from Sub In
is applied to the program bus ahead of the Master Faders,
thus the Master Faders control the Sub In level.
H. PLAYBACK INPUT JACKS Numbered 1 through 4,
the PB In jacks accept audio from a low impedance, low
level tape machine output. This audio is applied to the
PB side of the Direct/PB switch in the correspondingly
numbered Master and Monitor module. The PB In jacks
are designed for -20dB levels and accept XLR type 3-
pin male plugs. *
I. ECHO OUTPUT (FOLDBACK OUT) JACKS Carry
the console output from Echo Send 1 & 2 Masters.
The Echo Out jacks are transformer-isolated, nominal
*4dBm (for 600-ohm termination), and they accept
XLR type 3-pin female plugs." As discussed previously,
these jacks may be used to drive foldback (stage
monitor) amplifiers or performers' headphone
amplifiers.
J. TALKBACK OUTPUT JACK Carries the output of
the Talkback & Oscillator module, even if the module's
bus assign switches are not latched. The TB Out jack
can be connected to a power amplifier, directly to head-
phones, or to any point where the oscillator or talkback
signal is needed. For calibrated operation with optimum
fidelity, TB Out delivers +4dBm into a 600-ohm ter-
mination. The connector accepts an XLR type 3-pin
female plug. *
K. PHANTOM POWER SWITCH Connects the 48Vdc
phantom power supply to the center tap of all input
transformer primary windings. 24/32 consoles have
switches for each input. Recommended procedure
is to turn off the phantom power whenever condenser
microphones are not used; however, the "phantom"
switch may be left on without damaging most standard
microphones, line inputs, or the phantom supply.
*Refer to the Installation Section of this Manual for information
regarding the polarity of all ХІ В connectors.
